The world of technology is constantly evolving, with new breakthroughs and discoveries shaping the way we understand and interact with the world. From quantum physics to computational complexity theory, recent advances have pushed the boundaries of what is possible in math and computer science. In this article, we will explore two of the biggest breakthroughs that have captivated the tech world.

Quantum Entanglement and the Halting Problem
In 1935, Albert Einstein was perplexed by the concept of quantum entanglement. This phenomenon allows particles to interact instantaneously across vast distances, defying our intuition about the speed of communication. Alan Turing, a pioneering computer scientist, identified another problem in 1936 – the halting problem. This problem arises when computers get stuck in infinite loops, making it impossible to predict when they will cease their computations.
These concepts may seem unrelated, but in a landmark proof, they converged to unlock a cascade of solutions in computer science, physics, and mathematics. This breakthrough came in the form of computational complexity theory, a branch of theoretical computer science that explores the computational power of interactive proofs.
Imagine a police officer interrogating two suspects, referred to as provers. The officer cannot verify every detail of their stories, but by asking strategic questions and pitting the suspects against each other, inconsistencies can be revealed. In a fascinating twist, these suspects can share quantum entanglement, allowing them to coordinate their responses in a quantum mechanical manner. The main result of the proof is that even with this entanglement, the police officer (the verifier) can accurately determine the truth of complex mathematical statements.
This breakthrough suggests that a super-powerful quantum computer could potentially verify answers to seemingly unsolvable problems like Turing’s halting problem. By combining ideas from computer science, mathematics, and physics, this proof paves the way for a deeper understanding of the interconnected nature of these fields.
Untangling the Conway Knot
Mathematics is a field that continually challenges our understanding of complex problems. One such problem was the Conway knot, which had stumped mathematicians for over half a century. The question revolved around whether the Conway knot could be considered a slice of a higher-dimensional knot, a property known as sliceness.
Lisa Piccirillo, a graduate student at the time, found it baffling that such a seemingly simple question remained unanswered. Armed with determination, she started working on the problem, eventually capturing the attention of senior topologist Cameron Gordon. Together, they untangled the mystery and proved that the Conway knot was indeed not a slice.
While this may seem like a small victory in the grand scheme of mathematics, it highlights the interconnectedness of different branches of study. Knot theory is intimately tied to the study of three and four-dimensional spaces. By tackling a specific problem, Piccirillo opened doors to further exploration and understanding in these broader areas.
Digitizing Mathematics with Lean
The digital age has transformed nearly every aspect of our lives, and mathematics is no exception. At Imperial College London, Kevin Buzzard is leading an effort to digitize math using a software called Lean. This software draws upon a vast library of proofs and theorems to verify increasingly complex mathematical statements.
By teaching Lean the language of mathematics, Buzzard and his team are harnessing the power of computers to aid in the discovery and verification of mathematical truths. The software’s library is growing exponentially, encompassing hundreds of thousands of lines of code and becoming more adept at handling complex mathematical concepts.
While computers offer great potential in the field of mathematics, teaching humans to communicate their mathematical ideas in the language computers understand is a challenge. But as the software evolves and mathematicians become more familiar with this digital language, the possibilities for collaborative problem-solving and the emergence of new proofs are expanding.
